I haven't posted in a while because I've been busy on other things. I have recently made 2 vases with open segments made on my Muse laser. I found that the creation of a segment design to cut only takes about 2 minutes which allows you to make as many of that size as you want. The cutting is also fairly quick. The real advantage is in the prep work on the segment ( minimal sanding on glueing surface ) and the much easier turning (no sharp edges). I have a picture and more detail I can go into if anyone is interested in this approach.
